解决 ORA-12514: TNS: 监听程序当前没法识别链接描述符中请求的服务(转)

数据库忽然链接不上了，报出问题是ORA-12514：监听程序当前没法识别链接描述服务中请求的服务，因而请教老师，老师在网路上找到这篇帖子解决了个人问题。

 

 

系统环境：Oracle 11.2.0.1.0 R2

下面操做默认在安装Oralce数据库的服务器上运行。

1）确保Oracle 基本服务都已启动

    OracleDBConsoleorcl

    OracleOraDb11g_home1TNSListener

    OracleServiceORCL

2）打开命令行，使用 sqlplus nokia_user/oracle@202.206.0.233/orcl 命令登陆 oracle ，显示以下：

 

C:\Documents and Settings\Administrator>sqlplus nokia_user/oracle@202.206.0.233/orcl

SQL*Plus: Release 11.2.0.1.0 Production on 星期五 12月 23 10:37:52 2011

Copyright (c) 1982, 2010, Oracle.  All rights reserved.

ERROR:
ORA-12541: TNS: 无监听程序

在ORA-12541: TNS: 无监听程序 错误下，不管是否在本地登陆都是会提示ORA-12541: TNS: 无监听程序错误的

3）在命令行中，执行lsnrctl status

C:\Documents and Settings\Administrator>lsnrctl status

在这里能够看到监听程序参数文件的位置

 

4）修改监听程序参数文件

初次打开时，内容以下

# listener.ora Network Configuration File: C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST =localhost)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = C:\Program_Files\Oracle\DataBase_11G_R2

修改成：

# listener.ora Network Configuration File: C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = orcl)
      (ORACLE_HOME = C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1)
      #(PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\Program_Files\Oracle\DataBase_11G_R2\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = orcl))
      (ADDRESS = (PROTOCOL = TCP)(HOST =202.206.0.233)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = C:\Program_Files\Oracle\DataBase_11G_R2

SID_NAME，KEY 的值修改成要访问的oracle实例的名称，HOST 修为 oracle 服务器使用的地址

 

5）重启listener,在命令行中依次执行 lsnrctl stop，lsnrctl start

C:\Documents and Settings\Administrator>lsnrctl stop
